I've posted on this before about the exhausr leaks.. now PDs are pulling them and have in stalled detectors.

6 years, 2 Tsbs, lemon law buy backs.. media coverage.. and yet Ford still can't figure it out.

The only time Ford will act on this is when PDs start excluding the  PIU from the next round of purchases.

Next generation isn't that far away. I don't think Ford is worried about that right now. Not yet at least.

What? What happened?

They'd want to be giving PDs some pretty good assurances since they backed Ford so heavily. with PIU...

Except the cop(s) that have to drive the Poison Inhalation Utility (PIU)......

IMO looks like the exhaust tips are too short on it, they can extend them beyond the bumper like the civil Explorer, some "curb hopping" ability maybe diminished but the results would be a safer vehicle.

That makes sense except it's coming out of the HVAC system, that much has been determined. What they can't quite figure out is how and why.

All they can do right now is advise them to keep the recirculating system off if they're idling for long periods and install CO detectors while they try to come up with a permanent fix.

What? What happened?

You misssd my point. I don't think Ford is too worried about losing sales since the next gen is only 1-2 years away. Of course they're trying to find a fix, but to do that they need to find a cause first.

What? What happened?

One completely uneducated guess is if Ford is using a stainless steel flex connection in the exhaust at the engine...I would bet it is coming from that. I am just "spitballing" at this point...never been under the hood of the current gen Explorer or PIU..

This has been going on for a couple of years at least.   The fix isn't something as simple as a flex hose or exhaust tips.

 

And to think Fields wanted to extend this platform even longer.

I have been driving PIU vehicles now with my Sheriff's Office for several years now. What seems strange to me is it's not all the vehicles. My department has at least a couple hundred of these vehicles driving around and I have heard of one PIU being turned in for the exhaust fumes in the cab. Whatever is causing it is not consistent, and is either occuring as a manufacturer defect or being created with wear. I personally have not had this issue and my units idle forever, probably more then drive time due to checkpoints and other patrol activity.

That's part of why they haven't been able to pinpoint the exact source or find a fix is because it's so inconsistent.

We several new ones on order, this time I will be getting the Ecoboost version. One of the Deputies in my unit has one and it is definitely quick.. really impressed with how smooth the power is.

How well have your current units been holding up? The RWD Hemi Chargers have been unreliable with my Department (Indiana State Police). So now they decided to spend more money and have switched to AWD Chargers.  :doh:   Cant wait to see the maintenance nightmare these will be! I have not heard many complaints about them from the guys because they love how fast they are.  We started the switch in 2011 and still have about 1/3 fleet with CVPI, including me.  :victory:  They started using Tahoes for Commercial Vehicle Troops, but quit buying them due to cost.  Several  of them are still in  CVPIs with pretty high mileage due to not having a vehicle that can haul portable scales.  Last I heard, they looked at PIU but decided to get 4WD trucks, most likely Rams.  :doh:

This exhaust issue is being caused from WOT accelerations, not idling. It I
Happens with the 3.5 and 3.5 ecoboost.

They have tried installing new mufflers where the exhaust tips point down and it has helped but doesnt eliminate it.

It has even happened on the 16s and 17s but not nearly as often as the 11-15s. This is not a 2 year problem.. it has been going on for over 6 years.

It is entering from the rear (not the front).. whether the HVAC or the rear hatch.

So the RWD models were unreliable, so lets get the same thing with more complex AWD systems?  That makes sense...

That almost sounds like the PTU issues that Flex and others were having years ago.
